Determining motion using accelerometer data
Montilla, Michaela ; Koťová, Markéta (referee) ; Janoušek, Oto (advisor)
The aim of this thesis is to present the topic of acceleration record using accelerometer sensors and to create a program for the transformation of the acceleration data into the position vector. It is a summary of theoretical background of data recording using sensors of acceleration and an overview of the physical relationships between acceleration, velocity and position. The data was recorded by multiple types of sensors. The gist of the algorithm is a mathematical realization of physical relations modifying the conversion of acceleration to the position. The outcome enables to display a dynamic graphic output in 3-D.

The MEMS sensors usability for position detection
Bobalík, Lukáš ; Sedláček, Jiří (referee) ; Žák, Jaromír (advisor)
Within this Master’s thesis, design and construction of a strapdown inertial navigation system based on MEMS sensors is described. The thesis includes theoretic analysis of physics behind determining the position of an object based on the object’s aceleration and changes in the object’s orientation in space. Included is also an overview of mathematical methods related to the position calculation.

Selected Driving Manoeuvres of Motorcyclists
Kriegsmann, Luděk ; Bradáč, Albert (referee) ; Semela, Marek (advisor)
The entire diploma thesis is designed into two parts. The first part is focused on the theoretical description of the construction of motorcycles. In particular, the theoretical part deals with the description of the types of motorcycles, types of frames, types of suspension and the description of braking systems used on motorcycles. In the theoretical part, the main parameters of the motorcycle are also addressed, which affect the handling and stability of the motorcycle while riding. The last theoretical part deals with the technique of riding a motorcycle. The second part is focused directly on the execution of the experiment. The experiment consists of measuring five disciplines, namely measuring acceleration, measuring braking deceleration using brakes, measuring deceleration by the engine, measuring exit from an intersection and measuring lateral displacement. Eight motorcycles took part in the measurement. The main outputs from the measurements are time data, deceleration and lateral acceleration values.

Use of digital accelerometers in Linet bed controls
Dvořák, Ferdinand ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
The subject of this bachelor thesis is a design of methods for accelerometer usage in medical bed controllers in order to eliminate the activation button. In the introduction the Linet company is presented and the issue of legislation and safety of controling the medical beds is briefly discussed. This part is followed by a theoretical chapter considering MEMS technology and accelerometers. The metodology of reference and simulative signals acquisition is designed. These signals are then analysed. In following chapters the particular methods of solutions are presented. The comparison of the presented methods and the final summary of the thesis is included in the conclusion.

Hardware Acceleration of Cipher Attack
Okuliar, Adam ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Hardware acceleration is often good tool to achieve significantly better performance of processing great ammount of data or of realization of parallel algoritms. Aim of this work is to demonstrate resoluts of using FPGA circuits for implementation exponentially complex algorithm. As example haschosen brute-force attack on WEP cryptographic algorithm with 40-bit long key. Goal of this work is to compare properties and performance of software and hardware implementation of choosen algorithm.
